Your documentation points to a README.ks file in the doc
directory and this doesn't exist.
Secondly, your kickstart documentation states to use 'en'
for lang and this is in accurate as well. One of our
engineers was lucky enough to find the actual lang variable
of 'en_US' only as a matter of perseverance and a lot of
time.
Please correct your documentation and make this README.ks
file available to us somehow.
